From the Maldives to the Florida Keys, luxury resorts are doing more than offering pristine snorkeling — they are actively rebuilding the reefs that make those experiences possible.
Planning a vacation can be such hard work that you need, well, a vacation. From where to go and where to stay to what to do, it’s exhausting. Add to all the planning the desire to stay somewhere environmentally conscious, and the work can seem even more daunting. But things are changing, particularly for coastal destinations where reefs have become a primary consideration.
According to the Coral Reef Alliance, coral tourism generates an estimated $36 billion for the global economy each year, supporting millions of jobs and underpinning the entire business model of tropical resort travel. That number is increasingly at risk. From January 2023 through March 2025, bleaching-level heat stress impacted 84 percent of the world’s coral reef areas across 82 countries and territories — the most extensive coral crisis ever recorded. Half of all coral reefs have died since the 1970s, and scientists warn that between 80 to 90 percent are on track to disappear by 2050 without urgent action.
For the resorts built around reef access — the overwater villas, the dive programs, the glass-floor bungalows — this is much more than an abstract environmental problem. It is a direct threat to their very existence. “In the face of mounting threats to coral reefs, this multiplying effect is exactly what we need right now,” Susan Gardner, Director of UNEP’s Ecosystems Division, said of the growing coalition of conservation investment. For the hospitality sector, the math is becoming unavoidable: a dead reef means no reason to visit.
Hotel marine science programs
What was once a donation line item or a reef-safe sunscreen policy has, at a growing number of properties, evolved into full-scale marine biology operations — resident scientists, in-water nurseries, AI-powered monitoring systems, and guest programming that puts travelers directly in the water with coral fragments and zip ties. In other words, vacation activity planning sorted.
Steven Phillips, general manager of Finolhu in the Maldives, said last year that reef activities represent “a unique opportunity to unite resorts, share expertise, and promote marine conservation at the highest level. Healthy reefs are essential not only for the Maldives’ biodiversity but also for the well-being of local communities and the sustainable future of tourism.”
Science is providing reason for measured optimism. A 2024 study published in Cell Press found that restored coral reefs can reach full recovery in carbonate budget growth within four years — a meaningful signal that active intervention works and that the window for it, while narrowing, is still open.
Alicia Graham, general manager of Six Senses Kanuhura, said in a recent statement that the Kanuhura Coral Census marks “a major leap in reef science” within the hospitality sector. Graham says that by introducing advanced reef mapping, “we are not only elevating how reefs are monitored, we are transforming what is possible.” The resort recently launched what it calls the Kanuhura Coral Census, the first long-term 3D reef monitoring program ever implemented by a resort, developed in partnership with scientists from Newcastle University and University College London.
But that’s just the tip of the iceberg…er, reef. Scores of properties are now prioritizing reef restoration, and, increasingly, opening up these efforts to guests for more meaningful experiences during their stays.
Hotels and resorts with coral restoration programs
These luxury properties all have substantive, verifiable coral restoration programs — places where marine biologists are on staff year-round, nurseries are actively planted, and guest participation is woven into the experience.
Four Seasons Resort Maldives at Kuda Huraa
The longest-running resort-based reef restoration program in the world began here in 2001. The resort’s pioneering partnership with local environmental agency Reefscapers has produced more than 8,500 transplanted reef structures in the waters around two Maldivian islands, and the work has gone full cycle: frames planted years ago are now undergoing natural sexual reproduction. Guests have been invited to plant their own reef frame for over two decades, with growth tracked online at MarineSavers.com.
Six Senses Kanuhura, Six Senses Zil Pasyon, and Six Senses Malolo
Six Senses runs one of the most geographically broad conservation portfolios in luxury hospitality. At Kanuhura in the Maldives, the resort’s new Coral Census uses 3D modeling and AI analysis to map more than 1,000 square feet of reef per site, creating repeatable digital models that track bleaching events and habitat complexity over time. “It allows us to track even the smallest changes with scientific accuracy, share those findings openly, and make informed decisions that directly support reef recovery,” Graham said.
At Six Senses Zil Pasyon on Félicité Island in the Seychelles, corals in the resort’s restoration program grew over 200 percent on average in 2018, with a range of between 85 and 422 percent per harvested segment, in partnership with Nature Seychelles and the Seychelles National Park Authority.
The brand’s Fiji property adds a third node: Six Senses Malolo has planted more than 20,000 coral fragments across two nurseries, with seasonal guest programming running year-round.
Siyam World and Sun Siyam Iru Fushi, Maldives
The Sun Siyam group runs active programs across multiple properties. At Siyam World, resident marine biologist Thuhu and her team place coral frames that allow broken coral pieces to grow into artificial reef structures, with guests booking the experience directly through the resort app. Sun Siyam Iru Fushi’s Coral Restoration Project, led by biologist Mohamed Shah, collects naturally broken coral fragments and attaches them to frames in the resort’s lagoon reef — a system the property calls its “Nemo Garden” — before transplanting mature colonies to degraded reef areas.
Finolhu, a Seaside Collection Resort, Maldives
Finolhu distinguishes its program through collaboration. Rather than working in isolation, the resort convened marine biologists from Joali Being, Westin, Coco Palm, and Dusit Thani for a joint four-day effort that replanted approximately 1,200 coral colonies onto its house reef, including hands-on restoration dives, reef health assessments, and removal of invasive pincushion sea stars.
Banyan Tree Vabbinfaru, Maldives
Through the Banyan Tree Global Foundation, the resort opened a marine lab in 2004 that serves as both a research facility for scientists and an education center for local schools. Guests can help plant coral or clean algae off growing fragments in a coral nursery program that extends across three other Maldivian locations, with each site holding up to 1,000 fragments at a time.
Anse Chastanet, St. Lucia
Anse Chastanet operates the Caribbean’s only resort-based coral nursery program where guests actively participate in reef restoration. The Reef Life and Renewal initiative lets visitors earn PADI Coral Restoration Specialty certification while transplanting corals to Anse Chastanet Reef and Turtle Reef, with a goal of establishing 5,000 coral colonies. The resort also runs the Caribbean’s most distinctive conservation-meets-culinary crossover: an invasive lionfish eradication program in which guests hunt lionfish on morning dives and watch St. Lucian chefs prepare the catch the same evening.
Amanyara, Turks and Caicos
Set within North West Point Marine National Park, Amanyara’s Adopt-a-Coral program with Sustainable Oceans International lets guests sponsor a tagged coral fragment in the resort’s in-water nursery, traceable over time. The on-site Nature Discovery Center runs year-round programming with a resident naturalist, connecting guests to the reef through snorkeling expeditions, sea turtle monitoring, and marine biology presentations.
&Beyond Mnemba Island, Zanzibar
The resort’s Oceans Without Borders interpretive center supports a thriving coral reef nursery, active restoration of the Mnemba House Reef, and the development of expanding artificial reef structures. Twelve open-air bandas sit on a private island off Zanzibar’s coast, with no doors, no windows, and direct reef access from the shoreline.
Little Palm Island Resort & Spa, Florida Keys
The only private island resort in North America takes its proximity to the Florida Keys National Marine Sanctuary seriously. The resort’s collaboration with Mote Marine Laboratory has expanded reef restoration into Newfound Harbor, where guests can meet scientists, witness coral cultivation firsthand, and sponsor a coral throughout its growth cycle. A dedicated stay package includes a $500 donation to the lab; a full resort buy-out directs $5,000 per night to Mote’s research.
Kokomo Private Island, Fiji
Resident marine biologist Cliona O’Flaherty launched Kokomo’s Coral Restoration Project in 2018 with a focus on growing super coral capable of withstanding ocean temperatures that now regularly exceed 31 degrees Celsius on the Great Astrolabe Reef. The program was recognized by coral specialist Victor Benito as one of the best in Fiji, with around 4,000 corals transplanted back to the house reef by the program’s fourth year. O’Flaherty also helped advance a manta identification acoustic tagging program to track movement and increase protection for manta rays across Fijian waters.
Misool Resort, Raja Ampat, Indonesia
Perhaps the most ambitious conservation-hospitality model on this list, Misool operates within the most biodiverse marine environment on Earth. In 2005, a partnership between the resort and local communities created the region’s first No-Take Zone, now a 300,000-acre marine reserve encompassing two distinct no-take zones and a linking restricted-gear corridor leased directly from local villages. The Misool Foundation manages programs spanning reef restoration, marine governance, waste management, and community empowerment.
Nujuma, a Ritz-Carlton Reserve, Saudi Arabia
The newest — and most ambitious in stated scale — sits on the Ummahat Islands within Saudi Arabia’s Red Sea destination, part of the world’s fourth-largest barrier reef system and named Forbes Travel Guide’s 2024 Hotel of the Year. The developer, Red Sea Global, has committed to a 30 percent net conservation benefit to local ecosystems by 2040, with reef dives structured to contribute active data to conservation science through the property’s Conservation House program. Nearby, NEOM and King Abdullah University of Science and Technology have launched a coral nursery with a current capacity of 40,000 corals annually, scaling to 400,000 — positioned as a global blueprint for large-scale reef restoration.
